Initial research findings on three key domains of social development (attachment, empathy, and social competence) suggest that genetic factors contribute to individual differences in social development. Research on widely used measures of social environment implicates a genetic contribution. By the turn of the century, it is predicted that behavioral genetic research will be conducted using DNA markers that assess variation among individuals directly. This will revolutionize behavioral genetic research, making it more accessible and applicable to developmentalists.
